I was looking for a city tour that includes the Last Supper - since I waited too long to book my own reservation. It appears that Viator is the only company that offers a city tour of Milan - including the Last Supper? Does anyone know of another tour company? - Thanks
If you do a quick search, you'll notice that this is a frequent issue, as the online ticketing is less than reliable. If you haven't already, try calling anyway. Then ask your hotel to double check, many do this for free and may be able to get you something. I have never done this but I saw this online for Autostradale here that claims to allow you buy tickets online for a city sightseeing tour.
I booked the Last Supper tour for November, and am going on the "Zani Viaggi tour." I booked this through Expedia. I booked my whole trip through Expedia, and got a great deal!
Viatour is not a tour company, it is a ticket middleman.
The other tour provider that includes LS is the Autostradale city bus tour that CL mentioned, here's the link (I think it's the same link CL provided): Autostradale Milan Tours
